Common Alloys and Specifications of CNC Machining Aluminum

Because of some excellent properties like the ease of machining and good strength-to-weight ratio, aluminum is a popular CNC machining material for both prototypes and end-use products. You have a wide selection of aluminum alloys and grades for your milled or turned aluminum parts.
Properties Low density, high thermal conductivity, excellent corrosion resistance, good machinability
Applications (Aluminum CNC Parts) Aircraft fittings, spline shafts, medical parts, front panels, housing, dial and scales, etc.
Wall Thickness Determined by aluminum alloy and wall thickness-to-planar dimension ratios
Maximum Size Determined by machines and complexity of the part
Tolerances 0.005” or other tolerances based on the alloy
Lead Time As fast as 3 days, longer for complex custom aluminum parts

Aluminum 6061

6061 grade is the most commonly used aluminum alloy in the world, it is versatile due to its strength, machinability, weldability, heat treatability and more advantages.

Density Hardness Yield Tensile Strength Fatigue Strength Elongation at Break
2.7 g/cm^3 95 Brinell 276 MPa 96.5 MPa 17%

Aluminum 7075

7075 aluminum can be used as an alternative to 6061, this alloy has high strength and good fatigue resistance and corrosion resistance, 7075 aluminum parts are ideal for high-stress applications.

Density Hardness Yield Tensile Strength Fatigue Strength Elongation at Break
2.81 g/cm^3 150 Brinell 503 MPa 159 MPa 11%

Aluminum 6063

Aluminum 6063 possesses a higher corrosion resistance and formability than 6061 grade, but is not as strong as 6061. 6063 is more suitable to be used for exterior railings and pipings.

Density Hardness Yield Tensile Strength Fatigue Strength Elongation at Break
2.7 g/cm^3 73 Brinell 214 MPa 68.9 MPa 12%

Aluminum 7050

7050 can replace 7075 when strength is important, it has high toughness and high-stress corrosion cracking resistance, so common uses of 7050 aluminum including aerospace structures, fuselage frames and more.

Density Hardness Yield Tensile Strength Fatigue Strength Elongation at Break
2.83 g/cm^3 147 Brinell 490 MPa 160 MPa 11%

Aluminum 2024

2024 aluminum is also commonly used in applications requiring a high strength-to-weight ratio and good fatigue resistance, such as aircraft fittings and truck wheels, but it is not as strong as 7075.

Density Hardness Yield Tensile Strength Fatigue Strength Elongation at Break
2.78 g/cm^3 120 Brinell 324 MPa 138 MPa 19%

How to Choose Aluminum Alloy for Aluminum Machining Service?

The composition resulting in the difference between aluminum alloys, take a quick view of our chart of different aluminum properties and make the decision based on material characteristics and application requirements. Want to know the optimal material quickly? Welcome to send your inquiry to us fast.

Each alloy varies in its workability and its tolerance. Selecting an inappropriate alloy for aluminum CNC machining might make the operation considerably more difficult and flawed. Aluminum 6061 is generally the most popular alloy for machining. Its ratio of strength to weight, resistance to corrosion, and machinability make it more practical than others. However, for some applications, alternative alloys provide superior results, for example, aluminum 7075 is commonly employed for aerospace components.
